Terminal GNSS Antennas

In the last few decades, the variety of electronic terminal devices integrated with global positioning, navigation and time services has grown dramatically, so the design of terminal antennas for GNSS applications is attracting more and more interest. This chapter introduces three kinds of RHCP antennas commonly used for GNSS reception, namely microstrip patch antennas, quadrifilar helices and spirals. In addition, a novel PIFA antenna for GNSS application will be presented in the last section of the chapter.
